Walking into the ancient city, we went straight to the river. There are many cruise ships waiting for you. We didn't choose to ride. It's too hot. After walking along the river for a while, we enjoyed the scenery and hid in the shade of trees. Or come again at night, the street lights, lanterns, bridges on both sides of the river are lit up, and tourists put lanterns, gradually lighting the river, and then take the upstream boat to put the lanterns on the river by hand, very pleasant.
